Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Vehicle lost power while driving on a busy freeway and came to a complete stop and would not restart resulting in it being struck by a vehicle in the rear. More information available in the collision center pre estimate scan and full estimate.”

NHTSA complaint #11632849, filed 2024-12

“The vehicle suffered a total internal transfer case mechanical failure at 22,909 miles, which was documented during a factory-scheduled Service B check. The dealership attempted a fluid flush, which immediately resulted in an active 4MATIC system failure warning on the dashboard. Complete mechanical failure of this 4MATIC component causes extreme drivetrain binding and wheel hopping during low-speed maneuvers, presenting a major vehicle control hazard and a high risk of sudden loss of propulsion while driving on public roads.”

NHTSA complaint #11768362, filed 2026-10
